Galvanized lining systems

  Has anyone on the wall had any experience with rehabing galvanized water piping with an epoxy type lining?  I have seen some of the ads in PM magazine and at a few trade shows but have not seen and actual installation.

  My understanding is that they clean the debris out with a solution and then used high pressure airflow to dry it. Have not a clue how they apply the epoxy. Pros? cons?  Cost effective?

  I currently take care of about 2000 rental units with about 80% galvanized. We have constant issues with the hot lines. Would love to repipe with copper or pex but some of the buildings are tile block and plaster construction, others simply do not want the hassle of opening walls and floors.



Thanks in advance
